Hardware ReferenceTMP36 (Low Energy) driver

TMP36 (Low Energy) driver


The TMP36 (Low Energy) driver for temperature sensing is used in conjunction with the TMP36 sensor to measure the temperature of the sensor’s surroundings. This device supports ultra low energy mode and is only powered conditionally.

Driver Parameters

The TMP36 LE temperature driver for temperature sensing has three parameters that need to be configured:


This is the pin receiving the change in temperature from the TMP36.

Power Pin

This pin is selected to provide power to the TMP36 only during reading. This way we preserve power in the remaining time.


The resolution depends on the measurement system of the central core. If set to imperial, the resolution is in F (degrees Fahrenheit) and in metric it is in C (degrees Celsius).

The resolution in metric is ranging from 0 to 5 Celsius with a default value of 1.

The resolution in imperial is ranging from 0 to 9 degrees Fahrenheit with a default value of 1.

For example in in the metric system, if our latest reading was 25C and the resolution is set to 1.5, the builder base is not going to notify the central core unless the value is <23.5 or >26.5.



The GP0 pin is connected to Data Pin on the TMP36, the GP1 pin is connected to VCC on the TMP36 and GND pin on the Builder Base is then connected to the GND pin on the TMP36.

This pin provides the GND

How to write an App

Navigate to the App Builder and create a new application. You can find the “Temperature” code object under the “Hardware” Tab in the object drop down menu on the left, or you can also use the search bar.




Drag the “Temperature” Object onto the canvas.

Next, locate the “Text” Object under the Interface tab and drag it onto the canvas.




Finally, connect the “Temperature” port from the Temperature Object to the “In” port on the Text object and save your application.


How to create a firmware

Navigate to the Firmware Builder and create a new firmware file.

Click the “+ Add Hardware” button which will open a modal window. Scroll down in the list to find the “Sensor” section and select the “Temperature” hardware option.

Give your device a name, and click “Add Device”




Next, select the “TMP36” driver under the driver dropdown menu.



For this example we select:

  • Pin: GP0

  • Power Pin: GP1

  • Resolution: 1



You may now save your firmware file and upload it to one of your clients.
